Dust prevention compositions, coatings and processes of making

ABSTRACT

Compositions, applications, coatings, processes of making and applying compositions and compositions for preventing dust buildup on plastic and wood surfaces such as on ceiling fan blades, portable fan blades, stand fan blades, window blinds, appliances, furniture, cabinet knobs, and drawer pulls. The compositions and coating prevent dust buildup by (1) dissipating static charges on the blades and (2) creating a very smooth blade surface that prevents dust particles getting “captured”. The coating can have a clear matte finish and contains an anti-static and high lubricity additive to deter the accumulation of dust. After applying the coating the dry time of the coatings by thin coat gravure rollers is approximately four minutes. When applied the coating can result in up to approximately 50% less dust buildup over a one week period of time.

This application claims the benefit of priority to U.S. ProvisionalPatent Application Ser. No. 62/022,932 filed Jul. 10, 2014, which isincorporated by reference in its' entirety.

FIELD OF INVENTION

This invention relates compositions and processes for forming dustrepellant surfaces, and in particular to compositions, applications,coatings, processes of making and applying compositions for preventingdust buildup on plastic and wood surfaces such as on ceiling fan blades,portable fan blades, stand fan blades, window blinds, appliances,furniture, cabinet knobs, and drawer pulls, by (1) dissipating staticcharges on the blades and (2) creating a very smooth blade surface thatprevents dust particles getting “captured”.

BACKGROUND AND PRIOR ART

Dust buildup is known to occur over time, especially on stationaryproducts, and is undesirable. In addition to aesthetics, dust buildupcan spread germs and produce health related issues over time. Forexample, various types of products such as fan blades on ceiling fans,portable fans and stand fans tend to build up dust over time when not inoperation.

Current techniques to remove the dust buildup have centered on brushes,and the like. While the dust may be brushed off, the resulting fallingdust ends up spreading the dirt and further contaminating other surfaceson which the dust falls. Other techniques, such as washing the surfacecan further be tedious and undesirable since the maintenance would someitems, such as ceiling fans would require one to climb on a ladder,chair and the like, and can result in potential injury to the cleaner.

Various types of solutions have been proposed over the years. See forexample, U.S. Published Patent Application 2011/0076478 to Haynes.However, these types of coatings have not been universally accepted andcan cost extra undesirable costs that would make the underlying productcostly as compared to untreated products.

Thus, the need exists for solutions to the above problems with the priorart.
